Abstract: Methods, apparatuses and systems directed to refreshing signal information in an infrastructure wireless node location mechanism. The wireless node location mechanism selectively terminates connections with wireless clients to refresh signal strength information used to compute an estimated location for the wireless clients. The wireless node location mechanism terminates the connection between a WLAN and a given wireless node, causing in typical WLAN protocol implementations, the mobile station to transmit frames or packets on all available operating channels in a given band. This allows access points and other WLAN elements, operating on different frequency channels, to detect frames transmitted by the mobile station and provide refreshed signal strength information to a wireless node location mechanism.

Abstract: A method and apparatus for providing real time updates of a database describing the features of individual terminals of a shared plan telecommunications group for communication sessions from and to that individual terminal.

Abstract: A hierarchical cell structure (HCS) cellular communications system includes a macro cell encompassing a smaller micro cell that employ the same frequency band. The macro cell includes a macro cell base station, and the micro cell includes a micro cell base station. An uplink communication cell boundary between the macro cell and the micro cell is established, and a downlink communication cell boundary between the macro cell and the micro cell is established. A radio network controller determines whether a condition exists in the HCS system which indicates that the uplink and downlink micro cell boundaries should be unbalanced. If the condition is met or exists, the power and/or antenna beam tilt of a downlink transmission from the micro cell base station is reduced to unbalance the uplink and downlink micro cell boundaries. Alternatively, the radio network controller may employ an offset value to mathematically reduce mobile detected pilot power levels associated with the micro base station.

Abstract: One piece of information used in setting up the optimum location registration area is an area of a peripheral cell. However, in the current system, the area of a cell is set up by the predicted number of subscribers in the area, and therefore, depends on the location. Therefore, when a mobile communication terminal computes the optimum location registration area, it is necessary to obtain the size information about the peripheral cell, which can cause the problem of traffic. The mobile communication terminal in a cell signals a plurality of paging point nodes of mobility and traffic characteristic. Then, the plurality of paging point nodes sets up a location registration area of the mobile communication terminal according to the above mentioned information and network information. Thus, the location management of the mobile communication terminal can be efficiently realized, thereby reducing the traffic.
